fresh start- cutting

[trrz]

I always had a lean physique, but the last two to three years, I don't have any control over my bodyfat. Even with a strict diet it goes up. So, I want to make a new start with a new cutting diet:

my weight: 200 lb
bodyfat: between 16 and 18
age: 35

I want to follow this diet:

meal 1
- oatmeal: 100 g
- proteine shake: 50 g

meal 2
- apple

meal 3
- rice: 100 g
- 4 egg whites
- 1 egg
- vegetables

meal 4
- oatmeal: 50 g
- proteine shake: 50 g

meal 5
- potatoes: 500 g
- fish: 200 g
- vegetables

meal 6
- proteine shake: 50 g


Calorie: 2135
protein: 183 g
Carb: 290 g
fat: 27 g

I'm afraid that the total calorie are not enough. But I want definitely lose bodyfat
I accept all critique.
thx
